ENGINE.

Application `f1ed`J111y23, 1925. Serial No. 45,663.

The present invention relates to engines and particularly to internal-coinbustion engines; and its object is, generally, to provide an engine improved in various respects hereinafter appearing; and more particularly.v to provide improved valve mechanism for operating the engine; and further, to iu'ovide in'iproved charge-:tiring means for an, internal-combustion engine; and further,

` to provide improvedvalve inechanisn'l and charge-tiring means in combination.

These and any other objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the structure hereinafter particularly described in the body ot this specilication and illustrated by the accompanying drawings, in which:

Figure l is an axial sectional view of a portion of an internal-combust-ion engines cylinder and of its ports,iand showing its valves and means for operating the same, and its charge-firing means; y

Figure 2 is a transverse sectional view ot parts thereof taken on line 2-2 of Figure l;

Figure 3 is a view of one of the valves et the engine, partially sectioned diametrically to show parts within; and

Figure 4 is a top plan view of the same.

In the embodiment of the invention chosen for illustration by the drawings and :tor dey tailed description in the body of this specifications, an internal-combustion engines cylinder l with operating parts is shown. This cylinder has the exhaust port 41 leading from the cyliinlers head andl provided with a valve seat 42. The reciprocating valve 41:5 seating in this seat and controlling (he exhaust has an axially-extending Apassage 44 provided with ports 45 leading vfrom the conxbustible tluids intake 46, andhas also and at the inner end ot' said passage a valve seat 4T. A second valve 48 controlling the intake and seating in the seat 47 reciprocates in. said passage, sliding in a bearing 49 in the stem of valve 43. In the stem 5U oi valve 48 reciprocates a plunger 5l having at its inner end an electric Contact 52 adapted to engage the other contact 53 carried by the piston when the same is at or near its inmost position. after being moved inwardly by the lever 39, is suddenly withdrawn to disconnect these contacts, and thus tire the combusti The plunger,

ble fluid. charge, by a spring 54. The valves 425 and 48 are pressed into seating position hy the springs 55 and 56 respectively, spring 55 .being stiii'cr than spring 55, and spring 56 being stitier than spring 454. u

As indicated in Figure 1', the cylinder,the two `valves 43 and 4S and the plunger 5l through which extends` the electric con-` ductor 57, are axially concentric, so that the operation of introducing the combustible fluid into the cylinder, the operation of e1;- hausting theproducts oi' combustion therelrom and the operation of tiring the charge may all be as effective and suddenly complete as possible.

The lever Q engaging the upper end 4 ot the hollow stem of valve 43 moves it, against the pressure ot' spring 55, to open position; the lever 3 engaging the upper end 5 of the hollow stein of' valve 48 moves it, against the pressure of spring 56, to open position; and the levers 2, 3 and 39 are operated by rods 19, 18 and 40 respectively whose movements are governed, in properly timed relation, by any well-known means employed in such engines for operating their valves.v

The invention being intended to be pointed out in the claims, is not to be limited to or by details of construction of any embodiinenet thereof illustrated by the drawings or herenatter described. Y

I claim:

vl. In an internal-combustion engine: a cylinder having in its head an exhaust port; a piston in the cylinder; a reciprocating valve controlling said port and having an axially-extending passage provided with an intake port and a valve seat; a valve baving a reciprocating movement in and relatively to the first-mentioned valve and seating in the second-mentioned seat and controlling the intake port; an electric-conducting plunger slidable in the second-mentioned valve in its axial direction and having an electric Contact inside the cylinder; an electric Contact carried by the cylinders piston and adapted to be brought into and out of electric connection with the rst-mentioned Contact by the interrelative movements of port and a vulve seat; a valve having a. reciprocating,movement in and relatively to the first-mentioned valve and seating in the seconcl-rnenti`oned seat and controlling the intake port; an electric-conducting plunger elidable in the second-mentioned valve in its axial direction und having en electric contact inside the cylinder; :in electric contact carried by the cylinders piston and :adapted yto be brought into and out of electric connection with the irst-1nentioned Contact by the interrelative movements of' the plunger and the piston, the cylinder, the valves und the plunger being; substantially concentric axially. y

i 3. In un internal-combustion engine: n

cylinder having in its heed en exhaust port; :L piston in the cylinder; a. reciprocating valve. controllingr said port and having an axially-extending passage provided `with an intake port `and a` valve seat; :i valve having e reciprocating` movement in and relatively tric contact carried by the eylindes pistou and adapted to be brought into :md out of electricy connection Withlthe irst-1nentioned contact by the interrelative nlovelnents of the plunger und the piston, the vulves; being spring-pressed to seating position und sind plunger being spring-presned to seperate seid contacts: Ineens operated by the engine for moving the vulves 'from seating position and the plunger to contaets-ccnnectingir puerition in timed interrelution.

ln teetiinony whereof I beve hereunto set my hund at Grand Rapids, ll'liclxigun, `thie` 21st day of J11ly,1925.
